Forging presses

With open-die forging the workpiece attains its shape by changing the cross-section. The required shape is produced by multiple forging strokes, whilst simultaneously alternating between rotational and feed motion. The forging process is undertaken hot (retaining material strength), semi-cold or cold (increasing material strength). It requires extremely high forces (up to 1000 MN) and speeds (up to 120 strokes/min).

Requirements of components/ systems:

Temperature resistance
Shock resistance
Insensitivity to dirt
High accuracy of forging dimensions
High flow rates and high pressures
Energy efficiency

Rexroth solutions for forging presses:

Experience/ competence in the project design of “XXL Hydraulics”
- Customer-specific power units and control blocks
- Efficient, powerful hydraulic drives (e.g. A4VSO variable displacement pump)
- Special high pressure pumps for pressures of up to 450 bar (e.g. A4VBO variable displacement pump)
- For high flow rates: Valves of large nominal size (e.g. 2-way insert valves with directional function LC/LFA nominal size 160)
- For optimum control: Soft and fast-operating control valves (e.g. WRCE.../S)
- For high pressures: Valves with a pressure range of up to 1000 bar (special model)
